Claims (4)

  1. Elektrischer Warmwasserbereiter für ein geschlossenes Heizwassersystem, wobei der Warmwasserbereiter einen Wassertank und einen Flansch umfasst, wobei der Flansch mit dem Tank verbunden ist, mindestens ein Heizelement (3) sich vom Flansch in den Wassertank erstreckt und eine konzentrische Wand (5) im Wassertank angeordnet ist, wobei der Wassertank mit dem Kaltwassereinlass (1) und dem Warmwasserauslass (2) verbunden ist, dadurch gekennzeichnet, dass
    der Deckel (4) des Wassertanks aus einem zylindrischen Teil, der an seinem oberen Abschnitt am Flansch befestigt ist, und aus einem konischen Teil besteht, der an seinem unteren Abschnitt mit dem zylindrischen Teil des Deckels (4) des Wassertanks verbunden ist,
    die Form der konzentrischen Wand (5) dem zylindrischen Teil des Wassertankdeckels (4) entspricht und sich innerhalb des Wassertanks befindet, so dass zwischen dem Wassertankdeckel (4) und der konzentrischen Wand (5) ein äußerer Zirkulationskanal definiert ist,
    Heizelemente (3) sind in dem durch die konzentrische Wand (5) definierten inneren Zirkulationskanal so angeordnet, dass sie dazu beitragen, die Richtung und Geschwindigkeit des Wasserflusses zu ändern, wenn er sich durch einen Zirkulationskanal von oben nach unten und durch den anderen Zirkulationskanal von unten nach oben bewegt,
    der Kaltwassereinlass (1) ist nahe dem oberen Abschnitt des Wassertankdeckels (4) angeordnet und erstreckt sich in den Wassertankdeckel (4) und in den inneren Zirkulationskanal hinein, oder der Kaltwassereinlass (1) ist im Flansch angeordnet und erstreckt sich in den Wassertankdeckel (4) und in den inneren Zirkulationskanal hinein, der Warmwasserauslass (2) ist zum äußeren Zirkulationskanal hin offen und verläuft durch den Deckel (4) des elektrischen Warmwasserspeichers in der Nähe seines oberen Abschnitts,
    der konische Teil des Wassertankdeckels (4) einen Bereich (8) zum Absetzen fester Partikel aus dem Wasserstrom bildet und mit einem Ablassventil oder einem Anschluss (10) zum Anschließen eines Ablassventils versehen ist.
  2. Elektrischer Warmwasserbereiter nach Anspruch 1, dadurch gekennzeichnet, dass am Kaltwassereinlass (1) ein Deflektor (11) angeordnet ist, um das Kaltwasser gleichmäßig auf die Heizelemente (3) zu verteilen.
  3. Elektrischer Warmwasserbereiter nach einem der vorhergehenden Ansprüche,
    dadurch gekennzeichnet, dass Mittel zum Einsetzen mindestens eines Magneten (9) zum Abscheiden magnetischer Verunreinigungen im unteren Bereich des Wassertankdeckels (4) angeordnet sind.
